The Philharmonic Society of Orange County announced Monday that it will add four concerts to its 2014-2015 season schedule and will revive an old brand – Eclectic Orange – in the process.

None of the four events is strictly classical music, the Society’s bread and butter. In bringing back its Eclectic Orange nameplate, the group signals an expansion in its presentations. The Society first presented the adventurous, multidisciplinary Eclectic Orange Festival to great acclaim from 1999-2005.

“Our mission is to present the world’s greatest music. These Eclectic Orange presentations allow the Society to cross into other musical genres, and in doing so, serve more of the Orange County community, while maintaining the high caliber of artists that the Society is known for presenting,” said the Society’s president and artistic director, John Mangum, in a statement.

The added concerts are Mangum’s first significant curatorial move as the group’s new president. In June, he replaced longtime Society leader Dean Corey, who had already planned the current season. Corey planned the initial Eclectic Orange concerts.

The classical music comedy team Igudesman & Joo, the ukulele phenom Jake Shimabukuro, the tabla virtuoso Zakir Hussain and writer and radio personality Garrison Keillor will make appearances as part of the Eclectic Orange revival.

Igudesman & Joo will bring their show, “A Little Nightmare Music,” to Irvine Baclay Theatre on Feb. 18. The duo combines classical music, comedy and popular culture in the tradition of Victor Borge and Dudley Moore.

Shimabukuro, who has redefined the potential of the ukulele across a broad range of music, returns to Segerstrom Concert Hall on March 22. His program is still to be announced.

Hussain, a Grammy winner, will present his new show, “Celtic Connections: The Pulse of the World,” at Segerstrom on April 1. The concert combines traditional Celtic instruments with the tabla, bamboo flute, and Carnatic (south Indian) violin.

Keillor, the celebrated host of “Prairie Home Companion,” will offer a kind of one-man version of it at Segerstrom on April 13, telling stories and singing songs in collaboration with pianist Richard Dworsky, the musical director of radio show.

Single tickets go on sale for Eclectic Orange events Tuesday. For tickets or information, please call the Society at 949-553-2422, or visit philharmonicsociety.org.
